1. A method for monitoring of fluid composition using a field asymmetric ion mobility spectrometer, the method comprising:

  • (a) providing a first fluid sample;

    (b) generating a first time-averaged ion abundance profile corresponding to the composition of the first fluid sample;

    (c) providing a second fluid sample;

    (d) generating a second time-averaged ion abundance profile corresponding to the composition of the second fluid sample; and

    (e) detecting a change in the fluid composition by comparing the second profile to the first profile.
